i dont have anything to tune it currently. what options do i have for tuning. or anything besides a 500$ device? i always thought you could just take it to a dyno shop and they will run it and do it for you. but do you need the thing on your car for them to do it? is there any ways for me to pull my o2 sensors and clean them before i start running the mixed gas? i just kinda wanna run the mixed gas cuz i even noticed when i was on the east coast my car did have a slight difference between the 94 octane i found over there and the 91 we have around here. it ran a little rich but when i stomped on it, i could definitley notice the difference! and about my injectors.. how can i tell if they are oversized injectors?

you will need some sort of tunng devise and most start around $300 new then rnge up to almost $2k. I bought my SAFCII for $50 but that is becasue I bought it from someone who didnt know what it was

For about a month I ran mostly 100% 102 then I started doing a little mix for a while then my car went into mitsu for the wing and calipser inspection so I had to hide the SAFC and run 93 again, and since then I havent put it back in there. At this point my EVO hasnt moved in a fe months anyway. It has maybe 15 miles on it that I have put on since november.

102 was $3.95 when I started using it and the last amount I ai for it was $4.35 and that was when gas prices were threw the roof. I think C16 runs about $8 a gallon now maybe more but that is 116 octane

RE: running race gas

-unleaded race gas isnt going to harm your o2 sensors much at all.
-with stock injectors and nothing to tune with thetiny increase in powerisnt really worth the cost.
-you will only see a few more hp race gas depending on how much your car knocks on pump gas, the real power comes from being able to lean the car out since it is less prone to knock on race gas.
